Carburetor adjustment Basic information about the original carburetor setting The original carburetor setting was adapted for an altitude of approx. 500 meters (1600 ft.) above sea level, and the ambient temperature of approx. 20°C (68°F), mainly for off-road use and central European premium-grade fuel (ROZ 95). Mixing ratio 2-stroke motor oil : super fuel 1:40 . Basic information of changing the carburetor setting Always start out from the original carburetor setting. Essential requirements are a clean air filter system, air-tight exhaust system and an intact carburetor. Experience has shown that adjusting the main jet, the idling jet and the jet needle is sufficient and that changes of other parts of the carburetor will not greatly affect engine performance.

NOTE: If despite a changed adjustment the engine does not run properly, look for mechanical faults and check the ignition system. Basic information on carburetor wear As a result of engine vibrations, throttle valve, jet needle, and needle jet are subjected to increased wear. This wear may cause carburetor malfunction (e.g., overly rich mixture). Therefore, these parts should be replaced after 1000 hours of using. Idling range – A Operation with closed throttle valve. This range is influenced by the idle adjusting screw 1 . Only make adjustments when the engine is hot. The idling speed can be changed by turning the idle adjusting screw. Turning it clockwise produces a higher idling speed and turning the screw counterclockwise produces a lower idling speed. Opening up – B Engine behavior when the throttle opens. The idle jet and the shape of the throttle valve influences this range. If, despite good idling-speed and part-throttle setting, the engine sputters and smokes when the throttle is fully opened and develops its full power not smoothly but suddenly at high engine speeds, the mixture to the carburetor will be too rich, the fuel level too high or the float needle is leaking. Part-throttle range – C Operation with partly open throttle valve. This range is only influenced by the jet needle (shape and position). The optimum part-throttle setting is controlled by the idling setting in the lower range and by the main jet in the upper range. If the engine runs on a four-stroke cycle or with reduced power when it is accelerated with the throttle partly open, the jet needle must be lowered by one notch. If then the engine pings, especially when accelerating under full power at maximum engine revs, the jet needle should be raised. If these faults should occur at the lower end of the part throttle range at a four-stroke running, make the idling range leaner; if the engine pings, adjust the idling range richer

motorcycle can be kickstarted with the transmission in gear by disengaging the clutch before operating the kickstarter. Check the engine oil, transmission oil and coolant levels before starting the engine (page 21, 23, 24). Cold Engine Starting: 1. Turn the fuel valve ON. 2. Shift the transmission into neutral. 3. If the temperature is 35°C (95°F) or below, pull the choke knob fully out. 4. If the temperature is below 0°C (32°F), open the throttle two or three times. (The engine requires a richer mixture for starting in cold weather. When the throttle is so opened, the accelerator pump will feed extra fuel to the cylinder, thereby facilitating starting in cold weather.) 5. With the throttle closed, operate the kickstarter starting from the top of the kickstarter stroke, kick through to the bottom with a rapid, continuous motion. (Do not open the throttle, As the carburetor is equipped with an accelerator pump, excessive fuel will be charged into the engine, and the spark plug will be fouled if the throttle is opened and closed repeatedly. Excessive fuel in the engine makes kick- starting difficult.) 6. About a minute after the engine starts, push the choke knob back all the way to fully OFF. If idling is unstable, open the throttle slightly. (1) FUEL FILL CAP (2) BREATHER TUBE WARNING (1) FUEL VALVE (2) CHOKE KNOB Warm Engine Starting: 1. Turn the fuel valve ON. 2.

1. Protect the rear portion of the front fender with a towel or other thick, soft cloth. 2. Remove the OEM engine guards if they have been installed on the motorcycle. Or, if OEM engine guards are not present, Remove the two lower engine mount bolts. These bolts are located on the inside of the right and left frame rails, and will be replaced with the longer 10mm bolts included with your new engine guard. 3. Position the engine guard so that the lower brackets point towards the rear of the motorcycle, and slide the engine guard into the space between the front wheel and the frame. 4. Raise the guard until the upper V” mount is located between the frame rails. Note: Your new Barons engine guard is equipped with a unique upper V” mount clamp. This clamp becomes a cradle for the upper frame supports when it is inserted between the frame rails. 5. Rotate the engine guard until the lower mounting brackets are aligned with the lower engine mount holes. Due to production line tolerances in both the motorcycle and the engine guard, the mounting brackets may be too wide or too narrow for the frame. If this is the case, remove the guard from the motorcycle. Place the guard on a flat, firm surface. Insert a towel or other protective material between the guard and the surface. Using a rubber mallet or a block of wood and a hammer, tap the lower brackets until they are correctly spaced. 6. Insert the new 10mm bolts and washers, and finger tighten only. 7. Tighten each 3/8″ bolt in the upper clamp evenly by using a 9/16″ socket or a wrench. Snug down each bolt until it draws the front of the upper clamp into contact with the upper frame supports, then adjust these bolts accordingly to achieve equal spacing between each floorboard and the lower engine guard rail. 8. Tighten the jam nuts against the washers to lock each bolt in place. CAUTION! It is critical that you do not over-tighten these bolts. Tighten all remaining nuts and bolts securely. If necessary, slightly loosen rear brake line banjo bolt and rotate banjo fitting for clearance with engine guard. Tighten banjo bolt and check brake for proper operation. You must re-tighten all four of the engine guard mounting bolts after 100 miles of riding! Care & Cleaning: Engine guards take the full brunt of the worst of what the weather in your area has to offer, making it critical that proper and complete cleaning take place on a weekly basis, or corrosion will occur which is not covered by warranty! Proper cleaning procedure would be to use a product like Simple Green, LOC, Salt-Away or similar. Mix a strong batch and apply it liberally with a soft towel or soft nylon brush to the entire

Repair manual KTM 250 / 300 / 380 Art No 3206004 -E 2-2C main jet jet needle jet needle air control screw idle adjusting screw idle jet throttle valve Idling range A Operation with closed throttle valve. This range is influenced by the position of the air control screw 1 and the idle adjusting screw 2 . Only make adjustments when the engine is hot. To this end, slightly increase the idling speed of the engine by means of the idle adjusting screw. Turning it clockwise produces a higher idling speed and turning the screw counterclockwise produces a lower idling speed. Create a round and stable engine speed using the air control screw (basic position of the air control screw = open by 1.5 turns). Then adjust to the normal idling speed by means of the idle adjusting screw. Opening up B Engine behavior when the throttle opens. The idle jet and the shape of the throttle valve influences this range. If, despite good idling-speed and part-throttle setting, the engine sputters and smokes when the throttle is fully opened and develops its full power not smoothly but suddenly at high engine speeds, the mixture to the carburetor will be too rich, the fuel level too high or the float needle is leaking. Part-throttle range C Operation with partly open throttle valve. This range is only influenced by the jet needle (shape and position). The optimum part-throttle setting is controlled by the idling setting in the lower range and by the main jet in the upper range. If the engine runs on a four-stroke cycle or with reduced power when it is accelerated with the throttle partly open, the jet needle must be lowered by one notch. If then the engine pings, especially when accelerating under full power at maximum engine revs, the jet needle should be raised. If these faults should occur at the lower end of the part throttle range at a four-stroke running, make the idling range leaner; if the engine pings, adjust the idling range richer. Full throttle range D Operation with the throttle fully open (flat out). This range is influenced by the main jet and the jet needle. If the porcelain of the new spark plug is found to have a very bright or white coating or if the engine rings, after a short distance of riding flat out, a larger main jet is required. If the porcelain is dark brown or black with soot the main jet must be replaced by a smaller one. mixture too rich: too much fuel in proportion to air mixture too lean: not enough fuel in proportion to air 1 2 OPERATING RANGES OF THE CARBURETOR 2-3C Carburetor adjustment Basic information on the original carburetor setting The original carburetor setting was adapted for an altitude of approx. 500 meters (1600 ft.) above sea level, and the ambient temperature of approx. 20°C (68°F), mainly for off-road use and central European premium-grade fuel (ROZ 95 MOZ).
